I spoke to Arnaud Blandin (committer for Castor XML (because I only work on Castor JDO)) about this review, and he said that the reason the reviewer states that Castor XML doesn't support feature X is because she did not configure Castor XML at all.
I thought it was that Castor XML does not support XSD fully yet... but I can not say for sure. The only work I have done with Castor XML I was writing the XSD too, so could work around any possible problems.
